Analysis of the current Covid-19 infection and vaccination status in patients with neurofibromatosis type 1

Background: To investigate the common symptoms after Covid-19 infection, characteristics of adverse events after vaccination, changes in clinical manifestations related to Neurofibromatosis type 1 (NF1), as well as the current vaccination status and factors related to vaccine hesitation among NF1 patients, in order to provide a basis for scientific protection and vaccine acceptance in NF1 individuals in the new phase of pandemic management. Methods: From December 29, 2022, to January 10, 2023, we conducted a self-assessment questionnaire survey among diagnosed NF1 patients. General data were provided including sex, age, main clinical presentations, and current treatment. This study mainly focused on the infection and vaccination status of Covid-19 among these patients with NF1. The data were statistically analyzed using SPSS26.0 software. Results: Of the 250 questionnaires distributed, 226 were valid.
